salinity and a decrease in temperature as it 

 flows into the Weddell Sea. This modification 

 of properties is shown in a T-S diagram 

 (fig. 3) where an "upstream" station (sta. 31) 

 is compared to a "downstream" station (sta. 5). 

 These changes are probably due to freezing of 

 the shelf water as it flows south along and un- 



der the extensive ice shelves of the east coast 

 or surface cooling at the sea-air interface, 

 which may be very rapid during periods of 

 strong gradient winds. 



A temperature maximum of — 1.5 to — 1.6 °C 

 was found between 100 and 125 meters in the 

 Antarctic Surface Water at stations 5, 6, and 7
